It could be related to the ovirt-ovn-provider and/or its certificates, as
we get thousands of errors related to it inside engine.log

  $ grep ERROR /tmp/engine.log | awk '{print $4}' | sort | uniq -c
   2532
[org.ovirt.engine.core.bll.provider.network.SyncNetworkProviderCommand]

the last being:

2024-03-28 22:15:33,484+05 ERROR

Which version of oVirt are you using?

You could try to run this and see if it recreates certificates if this is
the problem (or if it asks to regenerate them, say yes). You should not get
downtime for VMs. The "--offline" option makes the command only refresh its
configuration without going through actual updates or modifications

engine-setup --offline

It restarts also the needed services (ovirt-provider-ovn too) in the
correct order, that could help sometimes

On the engine host
. check contents of /var/log/ovirt-engine/engine.log

. check the output of the commands:
systemctl status ovirt-engine
systemctl status httpd

. check contents of JBoss instance related logs
/var/log/ovirt-engine/server.log
In 4.5.x you should see something like this (see the deployed engine.ear
and ovirt-web-ui.war lines for example):

[ovirt-users] Recreate engine without backup

[Igor Filipovic via Users]

Hi all, 
I have a situation in which customer has deleted standalone engine completely 
(it was running on vmware), and all backups were saved on the same machine - so 
there is no backup available. 
Can someone suggest how to preserve virtual machines which are still running on 
kvm hosts, and recreate standalone engine to be able to manage existing kvm 
hosts and machines? What could be scenario for this?
Thanks in advance and best regards!
Igor

[ovirt-users] Re: Issue with Accessing oVirt Manager Console

[Sachendra Shukla]

Hi Alex,

After conducting a thorough check, we have confirmed that all virtual
machines are operating smoothly, and the network is functioning without any
issues (we can successfully SSH into both the VMs and the manager).
Additionally, there is available storage on both the node and the manager.
However, we are encountering difficulty accessing the oVirt manager
console, as we are consistently receiving a "503 Service Unavailable" error.

Thanks,
Sachendra
